General Information
This is the User’s guide for your Agilent E3633A and E3634A DC power
supplies. Unless otherwise stated, the information in this manual applies to
both two models.
This chapter provides a general description of your power supply. This chapter
also contains instructions for initial inspection, location and cooling for bench
and rack operation, selecting the power-line voltage, and connecting your
power supply to ac power.
Safety Considerations
This power supply is a Safety Class I instrument, which means that it has a
protective earth terminal. That terminal must be connected to earth ground
through a power source with a 3-wire ground receptacle.
Before installation or operation, check the power supply and review this
